Hi Larry I think Pete is saying the 25% chord line is swept forward slightly as it progresses outwards NOT the leading edge of the wing. The former being determined by the ratio of the leading edge angle to the trailing edge angle where the latter is proportionately greater. Nonetheless it is an interesting characteristic that we haven't known about or commented on before to my knowledge.
I think the KR sensitivity that some allude to stems mainly from the short fuselage and tail (maybe less so in the S series). My bird is stable as anything at the moment stuck in the hangar waiting for me to re do the cowl to suit the prop gearbox.
